This board is designed for ECEN-435 at the University of Nebraska-Lincoln (Scott Campus). GPS coordinates will print via CAN every 4 seconds. All GPS information sent over CAN is ASCII encoded. To obtain a lock, you must have a direct line of sight to the sky!! For CAN transmissions to work properly, the CAN resistor header (CAN R) must be shorted, allowing for proper termination.
Example Messages:
Message with no GPS Lock: LA00.00NLO000.0E
Message with GPS Lock: LA41.14NLO096.0W
CAN is enabled by default at 100 kbps with the following parameters.
